NO I was successful building with crossdev using: crossdev -t arm-unknown-linux-gnu However I wanted the Maverick FPU capability so after several attemps (all posted to this group) I got it to work. Here's what I did: Look carefully at the Web page Christopher has posted: http://perpetual-notion.blogspot.com/2008/02/maverick-crunch-eabi-support-for.html Down the page a ways, you can glean the 'heart' of Christopher's method: " and then create the toolchain. rm -Rf ${MAVERICK_OVERLAY} && mkdir -p ${MAVERICK_OVERLAY} && wget -O - ${OVERLAY_SRC}/maverick.tar.bz2 | \ tar xpjf - -C ${MAVERICK_OVERLAY} && PORTDIR_OVERLAY="${CROSSDEV_OVERLAY} \ ${MAVERICK_OVERLAY}" \ EXTRA_ECONF="--with-cpu=arm920t \ --with-fpu=maverick --with-float-abi=softfp" \ USE="-gcj -gtk -fortran -mudflap" \ FEATURES="buildpkg" \ crossdev -S \ --l 2.5-r4 --g 4.1.2 --b 2.17-r1 \ ${MYHOST} " For whatever reason it did not work as a whole ( not sure why) so I broke it down to several steps: Make dirs: cd /usr/local/portage/ mkdir crossdev_overlay mkdir maverick_overlay Download his 'maverick.tar.bz2' file I used a web browser can gleaned it to be in this dir (which is where I pointed my web browser): http://vaiprime.visibleassets.com/~cfriedt/maverick.tar.bz2 (does not seem to be working today) and unpack it in the dir he says to (see the above script): cd maverick_overlay/ tar xpjf ./maverick.tar.bz2 Then I just issued this command: PORTDIR_OVERLAY="/usr/local/portage/crossdev_overlay /usr/local/portage/maverick_ove rlay" ECONF_EXTRA="--disable-nls --enable-shared --with-system-zlib --without-includ ed-gettext --enable-threads=posix --enable-clocale=gnu --with-fpu=maverick --with-fl oat-abi=softfp --with-cpu=ep9312 --enable-languages=c,c++" USE="-gcj -gtk -fortran - mudflap" crossdev -S --l 2.5-r4 --g 4.1.2 --b 2.17-r1 armv4t-maverick-linux-gnueabi So this gets you a working cross compiler (which I have not used yet). The next step, which I have not had time to do, is follow the guidance of the folks at Imac who tell me putting a 32meg SD card into their board should allow me to boot off of several different images without removing their kernel: " The only thing I would add is that you can boot filesystems from the SD card. This will allow you to have your 2 bootable images. The kernel must be stored in the flash but this takes up much less room and you could easily store more than one. Example redboot command for booting from an SD card: load -v -r -b 0x80000 zImage-IPAC-9302-e1.2 exec -c "console=ttyAM0,57600 root=/dev/mmca1 rootfstype=ext3" This will load a kernel from flash into memory (SDRAM), and execute it with the boot args in quotes. The boot args here will tell it which tty port to use for console input/output, and specify the location of the root filesystem as being in the mmca device on partition 1 with and ext3 filesystem." So for now, that's all I have (consulting work keeps me running like an interupt processor with no return vector.....). If you read chris's page over and over, it becomes clear what he has done and what he is doing. If you cannot find the maverick.tar.bz2 file then ask Christopher to post it somewhere for you or provide a direct like. If you fiddle with his script, I'm sure you can get it to work natively...... Some of my make.conf entries conflicted, and I was too tired to reconcile all of that, at this time. HTH, James > And can you help me with building it natively?
